alt Hacker NewsIt used to be very common for migrants to change their surnames, although less so now. There used to be a person who wrote about Scottish Lithuanians called John Millar, who was born as Jonas Stepšys. Noam Chomsky had said that his family's surname was substantially altered after they went to the USA.
And older example: Warner brothers were born as Wonsal (or Wonskolaser), and they changed their names too (Hirsz became Harry, Aaron became Albert).
